THREAD PAR-TING AND HOLDING MEANS FOR LOOMS.

Specification of Letters Patent.

Patented Apr. 6, 1915.

Application filed July 7, 1914. Serial No. 849,605.

To all whom it may concern Be it known that I, ALoNzo E. RHOADES,

' a citizen of the United States, residing at Hopedale, county of \Vorcester, State of Massachusetts, have invented an Improvement in Thread Parting and Holding Means for Looms, of which the following description, in connection with the/accompanying drawing, is a specification, like characters on the drawing representing like'parts.

This invention relates to means for parting the thread or filling in a loom and also to means for catching and holding the end of the parted thread or filling when for any reason it is desirable so to hold such end.

The invention provides a novel means in a loom for parting the thread in that the thread is parted by abrasion, and particularly by the cooperating abrasive action of two surfaces.

The invention also provides a novel means for catching and holding the parted end residing in the use of a member provided with a thread adhering surface, and more particularly in a surface in which the thread adherent quality is secured by the fibrous condition of the surface, such for example as that presented by the edges of the superimposed washers of fibrous material such as felt or cloth.

The invention more particularly relates to looms of the type wherein the running filling is replenished prior to complete exhaustion, the old or spent filling being parted between the cloth and the shuttle, and the parted end caught and held to be carried into the path of a temple thread cutter or other suitable device for severing the filling close to the selvage. Features of the invention in this particular connection reside in applying to the face of the running shuttle an abrading member or surface in providing a cooperative member having an abrading surface movable into the path of the abrading surface upon the running shuttle so that when the movable member at the" required time is brought into the path of the shuttle the running filling is severed by the cooperative abrading action of the twoof thread parting means, and means for catching and holding the parted end embodying the invention, together with so much of the loom construction as is necessary to an understanding of the invention.

In the drawings, Figure 1 is a vertical cross sectional view of a portion of a loom of the Northrop type looking toward the hopper mechanism and showing in side elevation the parts particularly concerned with this invention the part 31 being shown in dottedlines for the sake of clearness; Fig. 2 is an elevation of the parts particularly concerned with this invention looking from a point in front of the lay toward the front of the loom; Fig. 3 is a top plan view of the main parts shown in Fig. 1; Fig. 4 is a side elevation of one end of a shuttle with the abrading member of this invention in position.

While the broad features of the invention are applicable to various means for parting thread in a loom for any desired purpose, the invention in its more specific form is concerned with the parting of the running filling prior to transfer in an automatic filling replenishing loom suchas that of the Northrop type. Mechanisms for securing this general object by other means are well known and familiar, and are commonly associated with or operated by the well known shuttle fecler mechanism or the mechanism which detects the presence of an improperly boxed shuttle and automatically prevents the transfer of filling taking place. The preferred construction of the present invention herein illustrated is for convenience shown in connection with a well known type of shuttle feeler mechanism, and is shown as having its operation effected by such shuttle feeler mechanism.

The construction of loom and shuttle feeler mechanism herein disclosed as a basis for the disclosure of the present invention is similar to that shown in the patent to Davis No. 1,08%,878 granted January 20, 1914:, and the patents therein referred to, but has one essential difference in that the shuttle feeler herein illustrated has no sliding movement axially of its pivotal axis because such movement is unnecessary when the present invention is used in the form illustrated.

The lay 1, the breast beam 2, the hopper stand 3, the notched dog 4 pivoted to the depending arm 5 of the transferrer, the controlling rock shaft 6 actuated upon the call for filling replenishment, and the vertical supporting member 7 of the loom side are all well known and familiar to this type of antomatic filling replenishing loom, and with their adjunctive features are more fully illustrated and described in the patents above referredto.

The shuttle feeler mechanism as already noted is of the general type shown in the patent to Davis above referred to, the construction being altered to provide for the elements embodying a preferred form of the present invention. A bracket 8 is bolted at 9 to the loom side and projects rearwardly therefrom. The shuttle feeler'lO is provided with a hub 11 offset from the shank or body of the feeler and pivoted or fulcrumed on a stud 12 projecting from the bracket 8. This shuttle feeler is provided on its shank with a hub 13 to which is'bolted the cam slotted arm 14 whichengages and operates the dog 4 to swing it into the path of a bunter upon the lay and" operates the transferrer mechanism in a well known manner. A pin 15 projects laterally from the shank of the shuttle feeler above its fulcrum and is operativelyconnected with the controlling rock shaft 6 by the arm 16 and jaw 17 governed by the spring 18. The jaw 17 is fulcrumed at the knife edge 19 on the arm 16. It will thus be seen that with this familiar construction upon the call for filling replenishment the arm 16 will be swung upwardly allowing the shuttle feeler 10 to swing rearwardly under the influence of the spring 18 and effect its functions in the usual manner. The shuttle feeler and actuating connections are shown in this position in the drawings. The rearward movement of the shuttle feeler is limited by a projection 101 from the shank thereof, engaging beneath a projection 102 from the bracket 8, while the forward movement of the parts is limited by another projection 103 on the bracket 8.

The features already described are all well known to those familiar with this type of loom except that it will be noted that the shuttle feeler 10 has no transverse movement but swings in a single plane, the trans-.

verse movement being unnecessary when the present invention in'its preferred form is employed. The remaining features illustrated in the drawings embody a preferred rides in a slot shown in form of the invention. A movable supporting member shown as an oscillating arm 20 is provided with a laterally projecting hub 2-1 journaled on the stud 12, and is held in place thereon by a washer 22 and a cotter pm 23. An arm 24 projects forwardly from and rigidly with the hub '21 and carries a pin 25 which alines with the pin 15 and likewise extends between the arm 16 and the jaw 17. The movable supporting member 20 serves to support and impart'movement to one of the abrading surfaces, thus to bring them into cooperative relation and enable the thread to be severed.v For this purpose in the form shown the movable supporting member-20 has at its upper end an elongated grooved head 26 in which is slidably mounted the shank 27 of the carrier 28. The carrier 28 is provided with a face which is struck by the lay as the lay beats up. The carrier is provided with the abrading member 29 which may be a piece of hardened steel presenting preferably a cylindrical abrading surface. This abrading member is prefer: ably a separate piece secured in place by screws 30. It will thus be seen that the two abrading members have a relative lateral movement to effect the abrading action caused in the form illustrated by the passage of the shuttle abrading surface 13 laterally past the abrading surface 29, and that they also have a relative transverse movement to bring them into cooperative relation caused in this case by the arm 20 being thrown rearwardly automatically at the required time-to carry the abrading surface toward the shuttle and the shuttle carrying its abrading surface 43 forwardly upon the beat up of the lay. The head of the carrier 28 is also elongated and carries at a position toward the center of the loom the thread catching and holding member 31 which as shown comprises a series of superimposed disks of felt, cloth or similar material, the cylindrical surface of which member thus presents a thread adherent surface, that is, a surface upon which the thread or filling ivill catch and be held by adhesion. This member need not necessarily be mounted upon the same carrier as the adjacent abrading member, as it is not essential that these two members shall be operated simultaneously and with the same extent of movement, but simplicity of construction and operation is effected by the arrangement illustrated and described. The shank 27 of the carrier is provided with a stud or pin 32 which projects through and dotted lines in Fig. 1 in the forward portion of the movable supporting member 20. A rearward movement toward the lay of the the movable member is efiected by an actuating lever 33, the upper end of which is slotted to engage a pin 34 projecting from the shank 27 of the carrier. This lever 33 carrier with respect to is provided with a hub 35 journaled on a pin 36 projecting from the shank of the supporting member 20 above its fulcrum. A helical spring 37 surrounds the hub 35 and engages at one end the lever 33 and at the opposite end a nut 38 on the stud 36. The lever 33 extends below its fulcrum point and the depending portion 39 contacts with a lateral projection 40 from the bracket 8.

The shuttle 41 is provided on its face adjacent the thread eye 42 with a cooperating abrading member which is herein shown as a small piece of hardened steel 13 secured by the screw 41 and presenting a cylindrical abrading surface.

The operation of the mechanism will now be apparent. Upon call for filling replenishment the controller rock shaft 6 is operatod to raise the arm 16. Spring 18 pulling upon the jaw 17 simultaneously swings the shuttle feeler 10 and the movable supporting member 20 rearward into the position shown in the drawings, this movement being limited by the stop projection 102. At the same time, the dog 4 is thrown by the connection 14 from the shuttle feeler into the path of the usual bunter. As the movable support 20 swings rearwardly it carries with it the fulcrum or pivot 36 and as the lower end of the lever 33 engages the fixed portion of the bracket the upper end of the lever 33 moves rearwardly under the influence of the spring 37, thus sliding rearwardly the carrier 28' with respect to the slotted head of the movable member 20 bringing these parts also into the position shown in the drawings. In this position the face of the carrier 28 is in position to be struck by the lay as it beats up, and thus the carrier is slid back in the head of the movable member 20 against the action of the spring 37. The abrading member 29 and the thread adherent member 31 which are mounted to project over the lay arecthus presented and maintained in operative position for securing their functions. As the shuttle is picked into the box'at the transfer end of the loom the abrading surface 43 carried thereby and over which the running filling extends from the thread eye 42 locks against the abrading surface 29 held yieldingly rearward, and the thread is parted bv the cooperating action of these two abrading surfaces. The parted end of the thread or filling extending from the fell is in contact with the thread adherent surface of the member 31 and is caught and held thereon by the adhesive action of the surface. The parts now return to their inoperative position and the parted end of the thread or filling adhering to the member 31 is carried forward and the filling passes into the field of action of the usual temple thread cutter in the usual manner, not necessary here to illustrate. While the member 31 moves forwardly in a rectangular direction the distance from it tothe point at which the filling end is held in the fell increases, but no lateral movement of the member 31 is necessary because the filling end being held by adherent action thereonmay slip or give with respect thereto without being pulled away therefrom.
